WOOD-TILE FLOORING.

SPECIFICATION forming part of Letters Patent No. 503,876, dat d August22, 1893 Application filed May 27, 1893. Serial No. 475,778. (No model.)Patented in Italy January 13, 1890,

To all whom itmay concern:

Be it known that I, ANTONIO SALVATIOO, of Garessio, Province of Oumo,District of Turin, Italy, have invented a new and Improved TileFloorlng, of which the following is a full, clear, and exactdescription.

I My invention relates to an improv'ementin tile fioorings, andespecially to an improvement in the construction of floors formed ofwooden tiles, which invention has been patented to myself in the Kingdomof Italy, the patent being contained in Vol. LII, No. 257, and its dateis January 13, 1890.

The object of this invention is to provide a tile floor of wood, inwhich the tiles may be made of any desired thickness and in which thetiles maybe laid close one to another at thelr upper or outer faces,while their under or lower faces will be grooved or channeled in suchmanner as to receive a sufficient amount of cement, glue, or othercementing material to maintain the tile blocks firmly and securely uponwhatever bed may be prepared to receive them, the engagement between thetile flooring and its support being such that the said tile flooringwill be practically soundless even when heavy objects are drawn over it.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth and pointed out inthe claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the views.

Figure 1 is a plan view of a section of the improved tiling. Fig. 2 is avertical section taken practically on the line 2--2 of Fig. 1.

Fig. 3 is a bottom plan view of a section of the tiling. Fig. is apartial plan view and partial sectional view of one of the tile blocks.Fig.5 is an end view of one of the blocks; and Fig. 6 is a sectionthrough a block, taken practically on the line 6-6 of Fig. 4:.

The tile blocks A are preferably made from wood, and they may be of anydesired shape. Ordinarily, however, they are made of the rectangular orsquare shape illustrated.

The tile blocks may be made as thick as in practice may be found mostdesirable, and

usually the blocks are of equal thickness to the boards usually employedin the laying of floors.

Each block is provided upon opposite sides with tongues 10, and upon theremaining two sides with grooves 11. The tongues are shorter than thelength of the sides at which they are located, terminating apredetermined distance back from the grooved edges of the sides. Thetongues are of different widths at the top and bottom, whichconstruction is clearly shown in Fig. 6, in which the narrow or top sideof the tongue is designated as a, while the under side, which is muchwider than the upper one, is designated as a, and the position of thetongues upon the blocks is such that they are much nearer the bottomthan the top surface of the blocks, being located below the longitudinalcenter of the side or edge of the block to which they belong. Thegrooves 11, extend the full length of the side or edge in which they areproduced,and occupy the same position in the sides or edges of theblocks as the tongues; therefore, since the tongues are wider upon theirunder than upon their upper faces, the lower wall of each groove isshorter than the upper one, as is clearly shown at the left in Fig. 4,and likewise in Fig. 3. One or more channels 12, are produced in thebottom of each block, and preferably the said grooves or channels arecircular and more than one is employed, in which event the grooves areconcentrically formed.

When the tile blocks constructed as above described are laid, thetongues of one block are made to enter the grooves of adjoining orabutting blocks, and their upper edges will be perfectly flush,contacting in such manner as to present hardly a seam or opening, asshown in Fig. 1, the close connection existing between the thickerportions of the blocks, that is, the side or edge portions above thegrooves and the tongues; but owing to the greater width of the lowerfaces of the tongues than the upper faces, the lower edges of twoopposing tile blocks will not engage; in fact, a groove or channel 13,will be formed between each two opposing or abutting blocks below thetongues, as is clearly shown in Fig. 3; and where four blocks arebrought together, at the junction of said blocks quite a depression 14,is formed, of essentially cruciform shape when the tile blocks are madesquare. I

The channels 13 between the tile blocks, and the depressions 14 betweenthe group of each four tile blocks, together with the channels 12 in thebottom of the tile blocks, are adapted to contain glue, cement, or othermaterial in which the tile blocks are to be laid in 5.11131- cientquantity to firmly embed them upon I and secure them to whateversupportmay be? prepared to receive them; and in this man ner each tile block ofwood, for example, may be as firmly, if not more firmly, laid than theordinary tile embedded in cement, and a floor is obtained which will bea positive non-eenductor of sound, while beautiful elfects may parquetteflooring, and it may also be made much thicker, and will consequentlypnod'uce a more solid --floori-ng, while it wilt-not be as cold as anordinary tile floor.

Patent- 1. A tile block, the same being provided with tonguesoflesslength than the sides upon, which they are located, the tongues beinglikewise of greater width upon one face than the other, and groovesproduced in other sides of the block, and having walls of unequallength,as and for the purpose specified,

2. A the block provided with tongues upon its side edges of less lengththan the edges to which they belong, the tongues being of greater Widthon one face than on the other,

block, and having walls of unequal length, 3 the tonguesand groovesbeing formed between the upper and lower faoes of the tiles, nearer oneface than the other, as and for-the purpose specified. '1 3. A tileblock provided with channels in its under surface, tongues uponitssideedges, the said tongues, being of less length than v the blockand bein-g ofi greaterw idtli ontheir under than their upper faces, andtongues in its other sides and having their lower walls shorter thantheir upper walls, the tongues 5 and grooves beingbel-ow thelongitudinal cenj ter of the edgesof the block, substantially as 5herein shown and described.
